Hi,
I recently acquired an original Automag R/T from a local. It had a problem of runaway. This is what I did so far to narrow down the problem.
Marker set up
Original R/T w/ level 7 bolt set up
Crossfire HP 800 PSI output tank
Wear to the components.
This marker needed a bit of TLC due to some hits on the marker itself. Sear looks clean and sharp. The bolt has some wear but not to bad. .750 on/off pin.
Replaced all seals. Oiled and greased seals and springs.
Checked and measure original on off pin. Why? I had an X valve with a short pin and had the same problem. Called AGD and they sent out a "stock" on off pin. Problem solved. This case original on off pin was .745" From all indications the pin was supposed to be .750. AGD techs said the .745 should have nothing to do with it and it will be a seal. My solution was to change out the pin to .750 or even to .755 to clam down the problem.
Result. The valve has become less runaway in the trigger compared to when I first recieved the R/T. However, I can still sweet spot the trigger. the difference between the 750 and 755 was very mininal.
I have never owned the original R/T. The ones I have seen seemed to shoot similar to the E mags, Retro Valves, and X valves. (I have owned all three!) From the reading the manual on line and watching the video, input pressure should really be around 700 PSI.
Are the original R/Ts really that finkey when it comes to input pressures? That extra 100 PSI really makes that much of a difference?
Are the original triggers really that senstive beyond 700 PSI?
Thanks for the answers,
Alan
